1. Cranial cavity filled with cerebrospinal fluid in an otter (Lontra longicaudis) - case report
RESUMO Realizou-se o exame tomográfico do crânio de uma lontra com histórico de incoordenação, déficit visual e convulsões. Imagens intracranianas revelaram grande lesão cística não captante de contraste em região frontoparietal esquerda, apresentando comunicação com o ventrículo lateral esquerdo e espaço subaracnoidea. Esses achados foram con

2. ATIVIDADE ANTICONVULSIVANTE DO ÓLEO DE PEIXE / ANTICONVULSANT ACTIVITY OF FISH OIL
Methylmalonic acidemias are inherited metabolic disorders characterized by methylmalonate (MMA) accumulation and neurological dysfunction, including seizures. Dietary fatty acids are known as an important energy source and reduce seizure activity in selected acute animal models. This study investigates whether the chronic treatment with fish oil or with olei

3. Estudo da anatomia endoscópica ventricular em cadáveres humanos brasileiros não fixados para realização de terceiro ventriculostomia / Study of ventricular endoscopic anatomy on Brazilian human cadavers non-fixed for the performance of the third ventriculostomy
INTRODUÇÃO: O objetivo desta pesquisa foi medir, através da endoscopia, o plexo corióideo no forame interventricular e estruturas no assoalho do terceiro ventrículo, bem como a distância entre as artérias comunicantes posteriores e comparar essas variáveis. MÉTODOS: Estudo observacional, prospectivo realizado em 37 cérebros de cadáveres humanos ad

4. Involvement of the heme oxygenase - carbon monoxide - cyclic guanosine monophosphate pathway in the nociception and antinociception induced by acute stress in rats. / Envolvimento da via heme-oxigenase-monóxido de carbono-guanosina monofosfato cíclico na nocicepção e na antinocicepção induzida por estresse agudo em ratos
A exposição de animais a situações ameaçadoras de natureza inata ou aprendida resulta em exibição de um repertório de comportamentos defensivos espécie-específicos, alterações autonômicas e em inibição da dor, sendo esse conjunto de reações de alta relevância para a sobrevivência de uma espécie. Considerando este contexto, um importante c

5. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

6. Hyperglycaemia, a morphine-like effect produced by naloxone in the cat.
In unanaesthetized cats the pronounced hyperglycaemia produced by intravenous morphine (5 mg/kg) was inhibited by naloxone. However, naloxone itself produced hyperglycaemia when given in doses slightly larger than those required to produce inhibition. These two effects of naloxone were obtained when it was injected intravenously, into a lateral cerebral vent

7. Prostaglandin D2, a cerebral sleep-inducing substance in monkeys.
The sleep-inducing effect of prostaglandin D2 (PGD2) was studied in five conscious male rhesus monkeys (Macaca mulatta) maintained in a 12-hr light/dark cycle. PGD2 was infused into the lateral or the third ventricle of the cerebrum slowly and continuously for 6 hr in the light period. Infusion of PGD2 into the lateral ventricle at 15-2250 pmol/min induced n

8. OLFACTORY BULB REMOVAL: EFFECTS ON BRAIN NOREPINEPHRINE*
Removal of one olfactory bulb causes marked changes in the norepinephrine contents of several brain regions. The brainstem catecholamine level is higher on the side of the lesion than on the control side, whereas telencephalic norepinephrine is lower ipsilateral to the lesion. The apparent decline in telencephalic norepinephrine is associated with a parallel

9. Enlargement of the third ventricle and hyponatraemia in aneurysmal subarachnoid haemorrhage.
Hyponatraemia following aneurysmal subarachnoid haemorrhage is associated with an increased risk of cerebral infarction. Whether the development of hyponatraemia was related to enlargement of the third ventricle on the admission CT scan was investigated in a consecutive series of 133 patients who were seen within 72 hours of aneurysmal haemorrhage. Hyponatra

10. Analysis of ceftriaxone and ceftazidime distribution in cerebrospinal fluid of and cerebral extracellular space in awake rats by in vivo microdialysis.
In vivo microdialysis was used to estimate the extracellular concentrations of ceftazidime and ceftriaxone, two expanded-spectrum cephalosporins commonly used in the treatment of bacterial meningitis, in two brain regions (the right corpus striatum and the left lateral ventricle_ of awake, freely moving rats. Antibiotics were administered by constant intrave

11. Single photon emission computed tomography in patients with acute hydrocephalus or with cerebral ischaemia after subarachnoid haemorrhage.
Using single photon emission computed tomography (SPECT), cerebral blood flow was studied in eight patients with gradual deterioration in the level of consciousness after subarachnoid haemorrhage. Four had cerebral ischaemia and four had acute hydrocephalus. In patients with cerebral ischaemia, single photon emission computed tomography scanning showed multi

12. Intracranial volume–pressure relationships during experimental brain compression in primates: 2. Effect of induced changes in systemic arterial pressure and cerebral blood flow
In eight anaesthetized, ventilated adult baboons, the intracranial volume–pressure response was examined at differing levels of raised intracranial pressure during induced changes in systemic arterial pressure and cerebral blood flow. The volume–pressure response is defined as the change in ventricular fluid pressure caused by a volume addition of 0·05
